98,590 | Rather, states are selected by a "non-computable" influence embedded in the Planck scale of spacetime geometry. Penrose claimed that such information is Platonic, representing pure mathematical truth, aesthetic and ethical values at the Planck scale. This relates to Penrose's ideas concerning the three worlds: physical... | Penrose–Lucas argument | 0.796107 |
98,591 | Both POM homopolymer and copolymer are stabilized to mitigate these types of degradation. In chemistry applications, although the polymer is often suitable for the majority of glassware work, it can succumb to catastrophic failure. An example of this would be using the polymer clips on hot areas of the glassware (such ... | Polyoxymethylene | 0.796107 |
98,592 | When this happens, the jump can be accompanied by violent turbulence, eddying, air entrainment, and surface undulations, or waves. There are two main manifestations of hydraulic jumps and historically different terminology has been used for each. However, the mechanisms behind them are similar because they are simply v... | Hydraulic jump | 0.796107 |
98,593 | One of the important developments arising from the geometric approach to mechanics is the incorporation of the geometry into numerical methods. In particular symplectic and variational integrators are proving particularly accurate for long-term integration of Hamiltonian and Lagrangian systems. | Geometric Mechanics | 0.796107 |
98,594 | However, alcohol consumption is known to increase the risk of liver injury in haemochromatosis. This finding is consistent with the concept that excess iron metabolism is a primary cause of haemochromatosis disease.Finally, in 1976, Marcel Simon and his collaborators confirmed that haemochromatosis is an autosomal rece... | Hereditary hemochromatosis | 0.796107 |
98,595 | The Cram's rule of asymmetric induction developed by Donald J. Cram in 1952 is an early concept relating to the prediction of stereochemistry in certain acyclic systems. In full the rule is: In certain non-catalytic reactions that diastereomer will predominate, which could be formed by the approach of the entering grou... | Chiral induction | 0.796107 |
98,596 | Yet on 17 July 2012, the FDA banned BPA from baby bottles and sippy cups. A FDA spokesman said the agency's action was not based on safety concerns and that "the agency continues to support the safety of BPA for use in products that hold food." Since manufacturers had already stopped using the chemical in baby bottles ... | Health effects of Bisphenol A | 0.796106 |
98,597 | In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram. | Regular pentagon | 0.796106 |
